Abstract
The reduction of Eu3+ to Eu2+ in SrB6O10 prepared in air by a high-tem perature solid state reaction was studied. The luminescent properties of Eu2+ in this matrix show f-d broad band emission peaking at about 3 86 and 432 nm at room temperature. A charge compensation mechanism is proposed as a possible explanation. The luminescence of Eu3+ with f-f transitions was studied in this sample and reflected that the Eu3+ ion occupied a site with non-centro-symmetry. The ESR spectrum was used t o detect the existence of Eu2+ in the samples. (C) 1998 Elsevier Scien ce S.A.
